Summary:Aluminium metal matrix composites have high strength to lightweight ratio. The AA2014/B4C/Graphite Hybrid Composites fabricated with different wt. % of reinforcement by stir casting. The Welding and Mechanical properties of hybrid composites were studied, and those results revealed that the SEM microstructure had shown the uniform dispersion of the reinforcement particles in the AA2014 with the addition of reinforced B4C and Graphite particles. The impact strength of the composite material is increased from 20 joules to 25 joules in the case of Izod test. Increase the tensile strength of welded composites up to 15.64% compared to base alloys. The hardness increased before welding 12.98% and after welding 38.32% compared to base alloys.
